1. NFC East: Washington Redskins

Cary Edmondson-USA TODAY SportsExpect Phillip Thomas to start at safety as a rookie.

The Washington Redskins got what they wanted from the 2013 draft in terms of help for a weak secondary. One of their top three picks will make the starting lineup as a rookie.

Defense

The safety position will see the most change for the Redskins. Fourth-round pick Phillip Thomas will partner with a fresh-from-injury Brandon Meriweather in the middle of Washington's secondary.

At cornerback, veterans Josh Wilson and DeAngelo Hall will remain in place. Second-round pick David Amerson will see plenty of action in the nickel. He'll line up on the outside when Hall covers the slot.

At linebacker, the Redskins will welcome back top pass-rusher Brian Orakpo. He'll continue forming a promising bookend tandem with Ryan Kerrigan on the outside.

The inside will be patrolled by the mixture of age and youth, offered by London Fletcher and Perry Riley.

Up front, Jarvis Jenkins will keep a starting role ahead of the recovering Adam Carriker. Barry Cofield and Stephen Bowen will continue to quietly excel at the other two spots.

While there will be an element of change on defense, expect things to look largely the same as 2012 on offense. The Redskins will start by relying on the same five offensive line starters as last season.

Pro Bowler Trent Williams is unchallenged at left tackle. Next to him, guard Kory Lichtensteiger remains a key blocker for the running game.

Center Will Montgomery and right guard Chris Chester round out a solid interior. At right tackle, things are little more sketchy.

2. NFC East: New York Giants

The New York Giants were smart to fortify their offensive and defensive lines in this draft. Like the Redskins, one of Big Blue's top three picks will start as a rookie.

Defense

That starter won't be on defense, although second- and third-round picks Johnathan Hankins and Damontre Moore will certainly contribute.

The Giants will keep Jason Pierre-Paul and Justin Tuck at defensive end. Moore will join Mathias Kiwanuka as a key member of the rotation.

Linval Joseph will be the nose tackle, and Cullen Jenkins will provide a pass rush along the interior. Mike Patterson and Hankins give the Giants enviable depth.

Linebacker has been a suspect position group for a while for Big Blue. Not much is different heading into the 2013 season.

Dan Connor should win the job in the middle. Jacquian Williams has the speed and coverage skills to take over from the departed Michael Boley on the weak side. Veteran Keith Rivers will be the other outside linebacker.

Last season's surprise package, Stevie Brown will start at safety, alongside the underrated Antrel Rolle. Expect Ryan Mundy to see plenty of action in coordinator Perry Fewell's three safety packages.

Corey Webster and Prince Amukamara will continue at cornerback. Aaron Ross will man the nickel position.

First-round draft pick Justin Pugh will be given a chance to start at right tackle. However, he may be best suited to a role inside as time goes on.

Initially, Pugh will fight to man the right side, according to The New York Times. Will Beatty remains at left tackle. Kevin Boothe and Chris Snee will be at guard, and David Baas will continue at center.

Brandon Myers was a smart free-agency signing, and he'll make an impact at tight end. Myers will prove to be a very useful outlet for standout quarterback Eli Manning.

Tom Coughlin will trust 2012's first-rounder David Wilson to be his main running back. Wilson's breakaway speed is something the Giants have rarely had at the position.

Andre Brown will need to stay healthy to provide a power-based complement to Wilson's quickness.

If there's one doubt about Big Blue's offense it comes at wide receiver. Hakeem Nicks will obviously start at one spot.

He remains as talented as any outside receiver in the NFL. However, the other position remains uncertain the longer Victor Cruz goes without signing a new deal.

Nobody has been tempted to trade for his services yet, but Cruz's unclear status has to rate as a worry. Louis Murphy should give the Giants a credible third wideout and a deep threat.

QB: Eli Manning RB: David Wilson FB: Henry Hynoski TE: Brandon Myers

OL: Will Beatty, Kevin Boothe, David Baas, Chris Snee, Justin Pugh

WR: Hakeem Nicks, Victor Cruz, Louis Murphy

The Giants look stronger up front on both sides of the ball after the draft. If Cruz remains in the fold, this roster is powerful enough to reclaim the NFC East crown.

4. NFC East: Philadelphia Eagles

Jeff Gross/Getty ImagesMatt Barkley won't the be day one starter for the Philadelphia Eagles.

The Philadelphia Eagles are undergoing a complete remake under Chip Kelly. Significant schematic shifts on both sides of the ball and a host of new faces do impact the starting lineup.

Defense

Kelly's shift to a hybrid 3-4 scheme dramatically alters Philly's defensive personnel. The change is most evident up front and will probably condemn former star Trent Cole to the bench.

Connor Barwin, a 3-4 rush linebacker, will play the joker end position. Brandon Graham will likely take the other edge position.

Isaac Sopoaga was brought over from the San Francisco 49ers to anchor the defensive line at nose tackle. Fletcher Cox should keep his place and play an under-tackle role in the ostensible three-man front.

The other position is up for grabs. Former undrafted free agent Cedric Thornton showed some promise last season.

However, he may find it difficult to fend off third-round pick Bennie Logan. Things are more clear at inside linebacker.

DeMeco Ryans and Mychal Kendricks will form a punishing combination. The major changes are found in the secondary.

Free agents Patrick Chung and Kenny Phillips will start at safety. The same scenario exists at cornerback, where Bradley Fletcher and Cary Williams should get the nod.

1. AFC East: New England Patriots

The New England Patriots have gotten younger and more dynamic at key positions. The wide receiver group has been overhauled, but the defense may have received the most immediate help.

Defense

Bill Belichick chose well when he selected Jamie Collins with his first draft pick. Collins has the hybrid skills to be the elephant-style rusher Belichick loves to use.

With Collins on one side and Chandler Jones on the other, the Pats will be able to neatly switch between a variety of defensive fronts.

Both edge-rushers will be helped by the interior dominance of mammoth duo Vince Wilfork and Kyle Love. Former Oakland Raider Tommy Kelly should also see the field and offers more of a pass-rush threat than Love.

Things are very clear at linebacker. Thumper Brandon Spikes is flanked by two equally big bruisers in Jerod Mayo and Dont'a Hightower.

New England fans will hope the secondary is better this season. The key to that will be an end-of-career flourish from the aging Adrian Wilson.

He should start at strong safety and give the Patriots defensive backfield the savvy it needs. Devin McCourty ought to continue at free safety, a role he is improving in all the time.

The cornerback spots look solid with Aqib Talib and Alfonzo Dennard. Their press skills are crucial to the Patriots' pressure schemes.

Expect third-round pick Logan Ryan to play a big role in sub-packages. He'll be joined by veteran Kyle Arrington.

2. AFC East: New York Jets

The New York Jets haven't been short of a few surprises this offseason. Their eyebrow-raising draft selections will help reshape the starting lineup.

Defense

Sheldon Richardson will start as a rookie and be ostensibly listed as the tackle of choice alongside Muhammad Wilkerson. They'll be joined by hulking veteran Antonio Garay on the rare occasions the Jets field their base 3-4 look.

In that set, Antwan Barnes and Quinton Coples will be the hybrid rush ends on the outside. Inside, the superb David Harris will join forces with DeMario Davis to man the middle.

Dee Milliner will begin life in the pros tasked with replacing Darrelle Revis. However, Antonio Cromartie will be the leader of the secondary. The disappointing Kyle Wilson will see time at third corner.

Dawan Landry will be a useful performer at one safety spot. He'll be joined by Josh Bush, who should man the free safety position.

The big question mark on offense is at quarterback. This author is predicting Geno Smith will snatch the starting job from Mark Sanchez.

Coaching in a contract year, Rex Ryan needs a bold move. It doesn't get much bolder than naming the controversial second-round pick as his starting quarterback.

Not to mention the fact the Jets need a major boost on offense. Sanchez has been well-below par in recent seasons.

The Jets were keen to acquire Smith, and there has to be a reason. It seems unlikely they were tripping over themselves to select a bench warmer.

Smith will throw to Santonio Holmes and Stephen Hill on the outside. He'll no doubt regret the fact Dustin Keller bolted to the Miami Dolphins.

Jeff Cumberland will replace Keller at tight end but won't be as prolific. Smith should enjoy throwing to third-down running back Mike Goodson, who will be invaluable.

He won't start, though, as that distinction will belong to trade pickup Chris Ivory. His power between the tackles will lead the running game.

Setting the table for this offense will be a remade offensive line. The overrated D'Brickashaw Ferguson will continue to fool many at left tackle.

Youngster Austin Howard will work on the right. Inside is where the Jets will be strong up front. Willie Colon will prove to be an inspired signing at left guard. He's a real force as a run-blocker. Center Nick Mangold will continue to dominate, but the right guard spot could see another rookie earn a starting berth.

Third-round pick Brian Winters is good enough to join the lineup and should win the starting right guard job.

3. AFC East: Miami Dolphins

Steve Mitchell-USA TODAY SportsDion Jordan will be a productive day one starter in Miami.

The Miami Dolphins were the big spenders of the offseason. Their starting lineups for 2013 will be littered with those purchases.

However, it is the player the Dolphins traded up to draft third overall who highlights this revamped team.

Defense

Dion Jordan will join a powerful defensive line to help produce a potentially devastating pass rush. The former Oregon ace will initially operate at weak-side defensive end in base 4-3 looks. The other side will be manned by the dominant Cameron Wake. These two rush-ends should savage quarterbacks this season.

They'll be helped by imposing tackle duo Paul Soliai and Randy Starks. Soliai's position will come under threat from former defensive end and 2010 first-round pick Jared Odrick.

The picture has also changed at linebacker. Landing Dannell Ellerbe from the Baltimore Ravens was a free-agency coup. He should occupy the middle linebacker position and become the focal point of this defense. Ellerbe will be flanked by newcomer Philip Wheeler and holdover Koa Misi.

Things will also look different at cornerback. Brent Grimes will take over a starting role after missing 15 games for the Falcons with an ACL injury in 2012.

Grimes will be partnered with Richard Marshall. Dimitri Patterson will be a sub-package cover man and also push for additional playing time.

The same is true for promising draftee Jamar Taylor. He should make things uncomfortable for Grimes and Marshall. Chris Clemons and Reshad Jones return at safety.

Ryan Tannehill will get the chance to iron out his inconsistencies as a second-year starter at quarterback. He'll be helped by improved targets in the passing game.

Mike Wallace offers the game's best deep threat on the outside. Brian Hartline is the ideal underneath complement on the other.

Brandon Gibson possesses big-play capability and will receive plenty of chances. Tannehill's most dependable option should be newly arrived tight end Dustin Keller. Fourth-round pick Dion Sims could also contribute. He has the potential to surprise and split time with Keller.

Things are unclear at running back. However, the brave move would be to feature Lamar Miller's versatility ahead of the more steady Daniel Thomas.

There may be bigger questions along the offensive line. Questions like: Who will play left tackle? At the moment it appears to be a battle between 2012 rookie Jonathan Martin and this year's third-rounder Dallas Thomas.

Martin should have the early edge, despite struggling through his debut pro season. Things are becoming more clear at right tackle.

4. AFC East: Buffalo Bills

The Buffalo Bills have certainly been more low-key than the Dolphins. However, there's still been a lot to like about the way they've been rebuilding.

The key to a quick revival will be the success of the choices they've made at quarterback. Those choices will involve starting a rookie.

Defense

It's not easy predicting the makeup of the Bills defense in 2013. New coordinator Mike Pettine has arrived from the Jets and already promised a multiple-front scheme.

What is clear is that imposing tackle tandem Kyle Williams and Marcell Dareus will be heavily involved. If Pettine shows some three-man or 46-style looks, they'll be joined by stout nose tackle Alan Branch.

Mario Williams and Mark Anderson can produce a more than credible pressure from the outside, while outside linebacker Manny Lawson gives the Bills a solid pass-rusher at the second level.

The inside linebacker role should be filled by second-round pick Kiko Alonso. He'll step in after the Bills traded Kelvin Sheppard to the Indianapolis Colts.

Nigel Bradham will take the other outside linebacker position. This gives the Bills a stronger-looking front seven.

Stephon Gilmore impressed as a rookie last season and will be Buffalo's premier cornerback. Leodis McKelvin should take the other spot.

Jairus Byrd will continue to be a prolific ball hawk at free safety. Da'Norris Searcy will be the safety playing closer to the line of scrimmage.

The Bills stunned the league when they drafted EJ Manuel 16th overall. They'll now go one better and start the ex-Florida State star ahead of veteran Kevin Kolb. Manuel's rookie year will be made easier by the dual-rushing threat of C.J. Spiller and Fred Jackson. Spiller will get the starting nod because of his game-stretching speed.

However, he'll share carries with Jackson in what will likely be a running back-by-committee approach. The same could be true at wide receiver.

Stevie Johnson often flatters to deceive, but remains this team's only marquee wideout. Second-round choice Robert Woods should win the other starting job. He's an intelligent route-runner and technically refined pass-catcher. Just the kind of dependable weapon a rookie passer will need.

T.J. Graham will be a fast-breaking slot receiver, as will third-round pick and one-time Olympian Marquise Goodwin.

There's undoubtedly a lot of youth and uncertainty at wide receiver. However, Manuel will at least be able to rely on competent tight end Scott Chandler. He's one of the most underrated players at his position in the NFL. At 6'7", Chandler will offer Manuel an easy target to aim for.

Keeping the rookie upright might be the toughest challenge the Bills face in 2013. Cordy Glenn is a massive left tackle with considerable skills, but the rest of the line looks dubious.

In the last two seasons the Bills have lost Demetress Bell, Andy Levitre and Chad Rinehart. What's left appears shaky.

Chris Hairston is likely to start on the right side. Eric Wood is a more than capable center, but there is some question about who starts either side of him. Converted center David Snow played guard briefly last year. However, Zebrie Sanders seems more skilled, if he can make the transition from tackle.

That would leave Snow to compete with Kraig Urbik for the right guard spot. Urbik would have the edge in that battle, as he will be vital in the running game.

Like the Eagles, it's all change for the Bills on both sides of the ball. Pettine's defense may have to emerge as strong enough to carry the team if Manuel struggles and given the inexperience at receiver.

1. NFC North: Green Bay Packers

Ron Chenoy-USA TODAY SportsDatone Jones will quickly become a key figure on the Packers defense.

The Green Bay Packers' 2013 draft class will play a major role in shaping their starting lineups. Most of the impact will be felt on offense, with a new running back added to the mix.

However, the best new addition could be found on the defensive line.

Defense

Top pick Datone Jones has the potential to be a steal for the Packers. Coordinator Dom Capers has already talked up what Jones will bring to his defense, according to The Milwaukee Journal Sentinel:

He's athletic and he's long, so he moves with ease. I think that he'll be able to give us rush inside.

In our 3-4, he can play out at defensive end, and he can be an inside player and do a good job against both the run and the pass inside.

Jones should start straight away at one defensive end position. Jerel Worthy should occupy the other. He was making a positive impression as a rookie in 2012 before sustaining an ACL injury. Jones and Worthy will flank one of the league's best nose tackles, B.J. Raji. This is a fearsome-looking defensive front.

Things still look strong at the linebacker level, thanks to the smart decision to re-sign Brad Jones. He'll partner with A.J. Hawk, whose reputation exceeds his ability, but the Packers don't seem to care.

Clay Matthews will continue to cause havoc on the outside. Last year's first-round pick Nick Perry should get another chance to prove he can offer a pass rush from the other side.

The cornerback positions look set with 2012's surprise Casey Hayward seemingly set for a starting role after snaring six interceptions as a rookie.

Tramon Williams will start on the other side. Sam Shields will see time in nickel and dime looks. Things don't seem quite as solid at safety, since the release of Charles Woodson.

Morgan Burnett will take one spot, and Jerron McMillian should beat M.D. Jennings to the other.

There's no danger of Aaron Rodgers not being under center in Green Bay. Now that he's armed with a bumper new contract, expect Rodgers to again push the Packers into the playoffs.

For the first time in a long while, Rodgers may even receive some help from his running game. The Packers drafted Eddie Lacy in the second round, and the former Crimson Tide ace should start.

He'll be pushed by fifth-round pick Johnathan Franklin. Rodgers now has credible options in the backfield. He has no shortage of those options at wide receiver, despite parting ways with Greg Jennings. Jordy Nelson and the fast-improving James Jones are two dangerous targets.

Randall Cobb can create big plays anywhere on the field and will be a bigger feature of 2013's offense.

Rodgers should also be pleased the Packers opted to retain tight end Jermichael Finley. Yes, he has drops and concentration issues, but Finley is as physically dynamic as any tight end in the NFL.

The offensive line in front of Rodgers has been dramatically altered. Reports in The Milwaukee Journal Sentinelsuggest Bryan Bulaga will switch from the right side to play left tackle.

Guard Josh Sitton will also shift to the left, while T.J. Lang will swap over and play right guard. Fourth-round pick David Bakhtiari will vie with Don Barclay, Marshall Newhouse and Derek Sherrod to play right tackle, according to Packersnews.com.

This author believes Bakhtiari will win that battle. Evan Dietrich-Smith will plug in at center.

2. NFC North: Minnesota Vikings

The Minnesota Vikings went all out in the draft to bridge the gap between themselves and the Packers. Each of their three first-round picks will be day one starters.

Defense

Defensive tackle Sharrif Floyd never should have fallen as far as the 23rd pick. Selecting him was probably one of the easier decisions the Vikings have ever made.

Floyd will start immediately alongside the aging but still effective Kevin Williams. They'll create trouble in the middle, to allow ends Jared Allen and Everson Griffen to flourish on the outside.

Chad Greenway will stand out at the linebacker level. He'll be joined by Erin Henderson and Audie Cole. Though rookies Michael Mauti and Gerald Hodges will push Cole for playing time.

The second of those three first-rounders, Xavier Rhodes, will replace the departed Antoine Winfield at cornerback. Josh Robinson will start on the other side, and the brittle Chris Cook should move to third corner.

Harrison Smith could be set for a monster season at safety. Smith will be the playmaker of the secondary. Jamarca Sanford will take the other safety spot.

The last of Minnesota's trio of first-round selections, Cordarrelle Patterson will step in at wide receiver and fill the void left by Percy Harvin.

Patterson will be helped along by stylish veteran Greg Jennings. Tight end Kyle Rudolph completes a promising group of primary receivers.

The pressure is now on young quarterback Christian Ponder to prove he's capable enough not to waste these weapons. The Vikings don't want to have to turn to Matt Cassel.

Of course Ponder's life will be made significantly easier by Adrian Peterson. The dominant running back won't be quite as prolific as last season, but he'll still terrify defenses. Peterson will again be aided by the brutal blocking of stout fullback Jerome Felton. He'll supplement the efforts of a solid front five.

That group will be led by combative left tackle Matt Kalil. On the right side Phil Loadholt isn't that far behind Kalil.

In the middle, center John Sullivan is the dominant force. Guard Charles Johnson and Brandon Fusco boast size and are solid interior pluggers.

3. NFC North: Chicago Bears

Keeping pace with the Packers and Vikings won't be easy for new Chicago Bears head coach Marc Trestman. However, the new regime in the Windy City has made several smart moves this offseason, especially improving the starting options along the offensive line.

Defense

The Bears can still rely on a powerful front four. However, veteran end Julius Peppers is no longer the star of the group.

That distinction instead belongs to nimble-footed tackle Henry Melton. His quickness and versatility allow the Bears the flexibility to run a variety of stunts and games up front.

Stephen Paea should take the other tackle spot and be a force against the run. Shea McClellin needs to rebound from a poor rookie season to fend off Corey Wootton at the final end position.

Things look a lot different at linebacker without Brian Urlacher. D.J. Williams will be a thumper in the middle, but can expect strong competition from second-round pick Jon Bostic.

James Anderson was an excellent signing to play outside linebacker. He gives the Bears more blitz skills than they've had at the position for a long time.

Lance Briggs should continue on the other side. He's still smart enough to mask his diminishing physical skills.

Cornerback is one of the easiest positions to predict on the Bears roster. Tim Jennings and Charles Tillman will start and continue to force turnovers at an alarming rate.

Big hitters Major Wright and Chris Conte will form a steady safety partnership.

The Bears have the talent to compete in the NFC North but have remade themselves at several key positions. They are also still reliant on veterans like Peppers, Briggs and Forte proving they have one or two productive years left.

4. NFC North: Detroit Lions

USA TODAY SportsEzekiel Ansah needs to be productive as a rookie for the Lions.

Despite some big-name talent on both sides of the ball, the Lions may struggle to compete in the North. They will hope a pair of promising draft picks and two marquee free agents can all make instant impacts.

Defense

The Lions are dominant at tackle, provided they can keep Nick Fairley healthy and Ndamukong Suh free from suspension. Fairley could exceed Suh's talents if he avoids injury.

Fifth overall pick Ezekiel Ansah will be counted on to make Lions fans forget about Cliff Avril and Kyle Vanden Bosch. The Lions certainly need the raw prospect to provide plenty of pressure off the edge.

The other end position might go to free-agent signing Jason Jones. He's talented but is better suited to tackle. Jones has struggled at end for both the Tennessee Titans and Seattle Seahawks.

It might be smarter to let Willie Young man the other end position. He's a more natural fit for the outside, particularly as a pass-rusher.

The Lions need all their strength up front, because the linebackers still look abysmal. Stephen Tulloch will continue in the middle but makes too many stops only after positive gains.

DeAndre Levy still hasn't fulfilled his potential on the outside. At the other spot, Tahir Whitehead or Travis Lewis must step in for Ashlee Palmer.

In fairness to the Lions, they have at least worked hard to make things look better in the secondary. Glover Quin was one of the best signings of free agency. He immediately upgrades the safety position. In fact, the Lions will actually now look strong there if Louis Delmas can stay off the treatment table.

Chris Houston is reasonably solid at one cornerback spot. If second-round pick Darius Slay makes a quick transition to the pro game, the Lions' coverage will be a lot better than in recent seasons.

Matthew Stafford continues to post gaudy numbers but also remains inconsistent. Granted, he hasn't exactly been helped by a feeble running game and a dodgy offensive line.

The first issue could be solved by Reggie Bush. The former Miami Dolphins starter is aging and has only posted a single 1,000-yard season in his career.

However, that came just two years ago, and he was a mere 14 yards short of the mark in 2012. Bush has proved he can be a feature back.

The key to his success will be improvement from the offensive line. Former first-rounder Riley Reiff will line up at left tackle. Things look better at guard, where third-rounder Larry Warford should join Rob Sims as a starter.

Dominic Raiola just never ages at center. Right tackle is anybody's guess. This author will speculate that Jason Fox wins the job. The Detroit Free Pressreported Fox intends to compete for a starting berth.

Thankfully, things are a lot more clear at wide receiver. Calvin Johnson is the one playmaker no defense seems to be able to cover.

Ryan Broyles is the best option to take some catches away from Johnson, provided he avoids injury. Nate Burleson is still around and will see plenty of playing time.

At tight end Brandon Pettigrew will again likely get the nod. However, like many on the Lions roster, Pettigrew is never as good as he should be.

QB: Matthew Stafford RB: Reggie Bush TE: Brandon Pettigrew

OL: Riley Reiff, Rob Sims, Dominic Raiola, Larry Warford, Jason Fox

WR: Calvin Johnson, Ryan Broyles, Nate Burleson

The Lions have talent in key areas but also inconsistency at those same positions. Their talent is also undermined by significant weakness at certain position groups, especially linebacker.

1. AFC North: Baltimore Ravens

The Super Bowl champions have worked hard to retool their defense after losing some key personnel. They will look to a pair of rookies to replace two all-time greats.

Defense

The Ravens have a plethora of options up front. Their best combination could involve Haloti Ngata at nose tackle with dynamic youngster Arthur Jones at one end and free-agent pickup Chris Canty at the other.

Canty is stout against the run, and the Ravens defense slipped to 20th against the rush in 2012.

Terrell Suggs and Elvis Dumervil give the Ravens a potentially devastating pass-rush tandem at outside linebacker. It's on the inside where things are more interesting.

Expect second-round pick Arthur Brown to take one spot. Jameel McClain should occupy the other. He's had his injuries, but McClain might still be a safer choice than Rolando McClain.

Safety will look a lot different without Bernard Pollard and Ed Reed. First-round draftee Matt Elam can be the thumper in the box that Pollard was.

However, hybrid cornerback Michael Huff will find it tough to replace Reed as the free safety.

At cornerback, Lardarius Webb's return from knee injury will be a massive boost. Jimmy Smith can build on a strong postseason showing by entering his second pro season as a starter.

Joe Flacco silenced most of his critics, this author included, with his flourish in the playoffs. He'll likely miss Anquan Boldin but still has Torrey Smith as a deep threat on the outside.

Tandon Doss is more of a possession receiver and offers the right complement to Smith. Flacco will also be able to rely on tight end Dennis Pitta. Ed Dickson will also see the field in two-tight end looks.

The offense might be strongest in the running game. Vonta Leach is perhaps the best lead-blocker in the NFL. He'll knock open holes for the dynamic Ray Rice to exploit. Bernard Pierce offers a great second option and shares the load with Rice.

The offensive line has been boosted by the return of Bryant McKinnie at left tackle. McKinnie dipped his toes in the free-agency waters, according to The Baltimore Sun.

The Ravens need him on the left and Michael Oher over on the right. Kelechi Osemele was one of a number of Ravens who came on strong in the playoffs.

He should start at left guard, with Marshal Yanda remaining a powerhouse on the right. Gino Gradkowski completes the line at center.

The Ravens have lost a lot, but they've also made some subtle additions that increase the flexibility of their schemes. Dumervil and Suggs give them two hybrid rush ends, enabling them to better disguise their fronts.

At lot will depend on the performances of Brown and Elam. If they quickly make the grade, the Ravens will still be as strong as any team in the AFC.

2. AFC North: Cincinnati Bengals

Frank Victores-USA TODAY SportsTyler Eifert will feature a lot for the Bengals.

The Cincinnati Bengals used the draft to get more dynamic on offense. Although their starting lineups won't alter dramatically, the Bengals' top picks will play prominent roles in 2013.

Defense

Cincinnati's stellar defense is led by a marauding front line that remains intact. That means Michael Johnson will continue causing havoc at one end spot and Carlos Dunlap will offer support from the other.

As good as those two are, it's inside at tackle where the Bengals are strongest. Geno Atkins is the most dominant interior pass-rusher in the league.

Things are very intriguing at the linebacker level. Former annual antagonist James Harrison should start on the outside. Even at 35, Harrison is still technically sound, smart and an explosive pass-rusher. Rey Maualuga and Vontaze Burfict are two bruisers. They will continue punishing running backs and receivers over the middle.

Leon Hall will start at one cornerback position. Graybeard Terence Newman will continue at the other spot until Dre Kirkpatrick proves his fitness and skill for the pros.

Adam Jones will play third corner. Reggie Nelson is the best safety on the roster but don't be surprised to see former Georgia star Shawn Williams paired with him.

Andy Dalton may have room to develop, but few can complain about his record of taking the Bengals to two straight playoff appearances.

The youthful quarterback will continue to fire passes to A.J. Green. Marvin Jones will partner with Green and labor to take some attention away from him. Andrew Hawkins is a natural fit for the slot.

Things don't look stronger at receiver, but Dalton will have better options at tight end. Top pick Tyler Eifert will form a dangerous tandem with Jermaine Gresham. If Eifert lives up to his billing, the Bengals' multiple-tight end sets could be among the best in the league.

The running chores should still primarily fall to BenJarvus Green-Ellis. He's a heady player and reliable between the tackles.

However, Green-Ellis should expect to lose some carries to second-round pick Giovani Bernard. The diminutive speedster is the classic change-of-pace back.

Both runners will benefit from the ferocious blocking form of fullback Chris Pressley. The blocking up front will also be strong with left tackle Andrew Whitworth the driving force for a capable line.

Andre Smith and Kevin Zeitler are a physical duo on the right side. Former Indianapolis Colts starter Mike Pollak should step in ahead of the disappointing Clint Boling at left guard.

The Bengals have given themselves more interesting options on offense and still boast a powerful defense. If the two-tight end sets take some pressure off Green, the Bengals will be playoff contenders again in 2013.

3. AFC North: Pittsburgh Steelers

Charles LeClaire-USA TODAY SportJarvis Jones will be counted on to replace James Harrison.

The Pittsburgh Steelers will count on their top rookie to keep a crucial area of their defense strong. However, there will be more pressure on a second-round pick to help create major change at running back.

Defense

The Steelers need more consistency from Ziggy Hood to match the talent that is obviously there. Brett Keisel is still reliable at the other end position. Cameron Heyward will push for playing time as well.

Steve McLendon will occupy the full-time role at nose tackle. He won't be as physically dominant as Casey Hampton. However, McLendon knows how to use his quickness and leverage to make plays.

LaMarr Woodley will continue to threaten offenses on the outside. The Steelers can also rely on savvy veteran Larry Foote and the versatile Lawrence Timmons to make plays in the middle.

The other outside position is a question mark. Jason Worilds has shown promise, but it's significant the team used a first-round pick on Jarvis Jones,

He'll take the starting job and is in the right scheme to flourish as a rookie.

Troy Polamalu and Ryan Clark are still a fearsome pair of safeties. At cornerback, Ike Taylor is as capable as most, and Cortez Allen and William Gay know the scheme well.

The biggest change in the Steelers offense will come in the running game. Second-rounder Le'Veon Bell has a great chance to be an immediate starter.

The Steelers ditched Rashard Mendenhall and could trade Jonathan Dwyer, according to ProFootballTalk.com. Bell should win the starting job ahead of LaRod Stephens-Howling despite the latter's familiarity with coordinator Todd Haley.

Will Johnson will consistently block open rushing lanes for Bell. Unfortunately, though, the running game may miss the blocking prowess of tight end Heath Miller.

He had ACL surgery in the offseason. General manager Kevin Colbert appeared to set a year as a time frame for his return, according to The Pittsburgh Post-Gazette. That could thrust David Paulsen into a starting role.

At least the offensive line should be strong, if only along the interior. Maurkice Pouncey is one of the league's best centers. David DeCastro proved a success as a rookie starter at guard.

Ramon Foster is a good run-blocker at the other guard spot. Tackles Marcus Gilbert and Mike Adams are weak, but the Steelers haven't been in a rush to upgrade them.

4. AFC North: Cleveland Browns

Al Bello/Getty ImagesBarkevious Mingo can start early in the Browns' 3-4 scheme.

A new regime has completely remade the Cleveland Browns defense. Those changes are crucial to creating a fast turnaround for a team that was 5-11 last season.

Defense

The decision to switch to a 3-4 base will be keyed by mammoth duo Phil Taylor and Ahtyba Rubin. Taylor should take the nose tackle spot, with Rubin at one end.

The other end position will be manned by free-agent arrival Desmond Bryant. This is a powerful-looking front three that already gives Cleveland's defense an intimidating appearance.

There are big changes at linebacker. Mega-bucks signing Paul Kruger will take one outside spot and be the unit's primary pass-rusher.

Sixth overall pick Barkevious Mingo will beat out 2011 second-rounder Jabaal Sheard for the other job. Sheard is more of a natural defensive end and doesn't fit well on the weak side.

On the inside, D'Qwell Jackson will be a leader and tackle everything that moves. It's the position next to him that will be contentious.

Craig Robertson could be a favorite. However, this author believes James-Michael Johnson is the better choice. Johnson is more of a big-bodied thumper, and that suits the requirements for a base 3-4 look.

Cornerback is a strong position as long as Joe Haden is on the roster. The Browns might have improved their options next to him after taking Leon McFadden in the third round.

He should win the job on the outside, with Buster Skrine moving into the slot in nickel situations.

T.J. Ward is a smart safety, but who occupies the other spot is anybody's guess. The lack of talent and options make sixth-round pick Jamoris Slaughter as smart a bet as any to start.

Weeden will fire any deep strikes toward Josh Gordon and Greg Little. They're both big speedsters. The trade for Davone Bess was a superb move.

It gives Weeden a dependable underneath option for when most of the coverage has been taken deep. Similarly, Jordan Cameron is built like a Turner-type tight end and should start ahead of blocker Kellen Davis.

Running back Trent Richardson can post big numbers in Turner's system. He'll be helped by a solid-looking offensive line.

Alex Mack anchors the front five as a skilled center. Joe Thomas is the star of the group as a physically punishing left tackle.

Jason Pinkston and Shawn Lauvao are two bruising guards who boast the size Tuner loves his lines to possess. Youngster Mitchell Schwartz completes a front five that should open plenty of holes for Richardson and keep Weeden clean.

Matt Ryan is fast becoming one of the best quarterbacks in the league. Few passers can match his accuracy and touch.

Ryan is blessed with arguably the best set of receivers in the league. Julio Jones is the deep burner who stretches coverage vertically.

Roddy White works the intermediate routes outside and across the middle. Classy veteran tight end Tony Gonzalez is the ideal foil underneath. Third wideout Harry Douglas is perfect for the slot.

What makes this offense truly scary heading into 2013 is the addition of Steven Jackson at running back. He's a major upgrade over Michael Turner, offering more big-play potential and greater receiving skills.

Sam Baker and Lamar Holmes are competent at both ends of the offensive line. Youngster Peter Konz can develop into a quality center, while Justin Blalock and Garrett Reynolds are solid guards.

There are still, rightfully, doubts about Mike Nolan's defense, in terms of both personnel and play-calling. However, this offense is strong enough to make the Falcons major players in the Super Bowl race.

Cam Newton wasn't at his rookie level in 2012 but still remains a prominent playmaker. He'll still throw to Steve Smith, and that can't be a bad thing.

Domenik Hixon will compete with Brandon LaFell for a starting berth. Hixon has a good shot to win that job.

Greg Olsen is another target for Newton to aim for. Newton could also benefit from more clarity in the running game.

The fullback position is set with Mike Tolbert, who is a capable blocker, receiver and runner. It's the running back position that remains unclear. DeAngelo Williams' return to the team is still far from certain, according to CBS Charlotte. That could leave Jonathan Stewart as the starter.

The offensive line is led by left tackle Jordan Gross. Amini Silatolu is a solid left guard, and Ryan Kalil is capable at center.

Geoff Hangartner fills in at right guard, while Byron Bell could be upgraded at right tackle.

3. NFC South: New Orleans Saints

The New Orleans Saints will be counting on key picks from their draft class to help out right away. The most important additions will be on a defense transitioning to a 3-4 scheme.

Defense

Third-round pick John Jenkins is a good bet to win the starting nose tackle job in coordinator Rob Ryan's new 3-4 front. Ryan still plays with a lot of two-gap principles and likes size up front.

Jenkins offers that and is a more natural fit than 4-3 nose tackle Brodrick Bunkley. Cameron Jordan and Akiem Hicks should take the defensive end spots, with Ryan-favorite Kenyon Coleman in reserve.

Hicks is definitely one to watch in this scheme.

Victor Butler played for Ryan in Dallas and offers above-average pass-rush skills at outside linebacker. Martez Wilson should be the other outside linebacker. However, don't rule out rookie free agent and ex-Stanford star Chase Thomas.

Inside linebacker is well-stocked with Curtis Lofton and Jonathan Vilma. The latter has played in a 3-4 in the past with the Jets and his schematic experience will prove invaluable.

The safety position was strengthened by the Saints' decision to select Kenny Vaccaro with their first pick. He'll join Roman Harper, to give Ryan two interchangeable blitzers and box defenders.

The Saints made another smart move when they signed Keenan Lewis to start at cornerback. The former Steeler will be partnered with Patrick Robinson on the outside.

With Drew Brees throwing the passes, the Saints will never be too far from contention. The record-setting quarterback will again have the luxury of throwing to a versatile group of receivers.

The group is led by Lance Moore, the pint-sized marvel who can exploit every level of a defense. Marques Colston continues to be reliable from anywhere across the formation.

Tight end Jimmy Graham is one of the most dangerous pass-catchers in football. Brees never tires of looking his way.

Things may look a little different at running back, where Mark Ingram appears ready to play a bigger role. Yet that still won't stop Darren Sproles from featuring a lot in the passing game.

It's up front where the Saints don't look as strong as usual. If they're smart, they'll plug in third-round choice Terron Armstead at left tackle ahead of Charles Brown. Armstead may be raw, but he's more physically gifted than Brown, who might fit better on the right as a viable alternative to former St. Louis Rams disaster Jason Smith.

The Saints can actually afford to risk an untested tackle due to their strength along the interior. This line has been built to reduce and hold the middle and allow Brees to see over a pass rush and down the field.

There are few better guard tandems than Jahri Evans and Ben Grubbs. Brian de la Puente is the kind of crafty technician every center should be.

4. NFC South: Tampa Bay Buccaneers

Kim Klement-USA TODAY SportsJohnthan Banks will be a key addition to a revamped secondary.

The Tampa Bay Buccaneers made themselves contenders in the NFC South by fixing the worst-ranked pass defense from 2012.

Defense

That process was started by sending a first-round pick to the Jets for Darrelle Revis. The dominant cover ace will be expected to shut down his side of the field. By itself, trading for Revis was a good enough move. However, the Buccaneers made it a great offseason when they selected Johnthan Banks in the second round.

Banks will start at corner, but he has experience playing at safety and could eventually move there, following the same career path as franchise-great Ronde Barber.

1. AFC South: Houston Texans

The Houston Texans will be hoping they have gotten better on offense, specifically in the passing game. They could also be boosted on a defense from an unlikely source—a defensive tackle taken in the sixth round.

Defense

J.J. Watt will continue being the most destructive defensive end in football. Antonio Smith will take the other end position and create his own share of problems for offenses.

Those positions are set, but nose tackle is far from certain. Holdover Earl Mitchell seems like an obvious choice to claim the starting job.

However, sixth-rounder Chris Jones is a viable dark-horse candidate to upset the odds. He's light for a nose tackle, but that suits what coordinator Wade Phillips likes at the position.

Jones is also a good pass-rusher. He posted 12 sacks last season for Bowling Green, according to CFBstats.com. A nose tackle who can rush the passer is something else Phillips likes.

Remember, it was Phillips who started Jay Ratliff at nose tackle in Dallas. Ratliff was an undersized defensive tackle taken in the seventh round by the Cowboys.

Brooks Reed will man one outside linebacker spot. Whitney Mercilus should take the other and live up his 2012 first-round-pick status.

Matt Schaub will stick at quarterback. He knows head coach Gary Kubiak's system well, but must prove he can deliver in the games that matter most.

Schaub could be helped by the arrival of a new playmaking receiver. The Texans were smart to use the 27th overall pick on DeAndre Hopkins.

They need a big-play threat on the outside to take the pressure off main wideout Andre Johnson. Hopkins' arrival means Keshawn Martin should move to the slot.

Owen Daniels is still as reliable as any tight end in the game. He's a key part of every aspect of the Texans offense.

That offense is keyed by the running of Arian Foster. The savvy zone-rusher will again lead a potent ground game ahead of able deputy Ben Tate. Garrett Graham will replace James Casey as the de facto fullback. The Texans will still rely on a stable, excellent offensive line, brimming with Pro Bowl talent.

The Texans have to hope Hopkins will provide an extra spark for their offense. They also need Phillips' defense to get back to its 2011 level. That'll happen only if Mercilus emerges as a prolific pass-rusher.

2. AFC South: Indianapolis Colts

Al Bello/Getty ImagesBjoern Werner will likely be a situational player as a rookie.

The Indianapolis Cots played their way to a remarkable turnaround in 2012. However, their starting lineups for 2013 will look a lot different after a number of contentious offseason moves.

Defense

Brilliant veteran Cory Redding will continue to occupy the under-tackle role in the Colts' hybrid 3-4. Former San Francisco 49er Ricky Jean-Francois will slide out to the other end after rugged old pro Aubrayo Franklin was added to play nose tackle.

At outside linebacker, Robert Mathis proved he can be every bit as effective in a 3-4 as he was in a 4-3. He's an exceptional player, and top draftee Bjoern Werner will benefit from learning behind Mathis in a situational role.

The other outside linebacker position will belong to Erik Walden. The Colts parted with a small fortune to sign Walden from the Packers, even though he was never special in Green Bay.

Walden at least gives the Colts a more versatile fit for the demands of a 3-4 scheme. The linebackers are strong inside with tackling machines Pat Angerer and Jerrell Freeman.

LaRon Landry must avoid injury and be the dynamic box safety the Colts need. Antoine Bethea will play the other safety role.

Greg Toler and Vontae Davis will man the cornerback positions. Darius Butler is an opportunistic third corner.

Andrew Luck could be dominant in his second season. The young quarterback will learn from his mistakes and reduce his number of interceptions.

The Colts will still rely on Vick Ballard to give him help in the running game. Stanley Havili's lead blocking could boost that running game.

Dwayne Allen should continue to outshine Coby Fleener as a more complete tight end. However, Fleener will still see the field in two-tight end looks.

It was a real privilege to watch Reggie Wayne make Luck's job easier last season. The aging receiver will be back to make all the catches again as the Colts' primary receiver.

Darrius Heyward-Bey has never lived up to his billing, but he does at least give the Colts size and legitimate deep speed on the other side. T.Y. Hilton will create his own share of big plays from the slot.

The offensive line still rates as a concern. Anthony Castonzo isn't the most agile or powerful left tackle. He could be helped by the arrival of Donald Thomas to play left guard.

Thomas is the best of the Colts' offseason acquisitions. He's a brutal force in the running game and stout in pass-protection.

Center Samson Satele needs to be pushed by fourth-rounder Khaled Holmes. Another rookie, Hugh Thornton, should supplant Mike McGlynn at right guard.

At least right tackle looks a little better thanks to free-agent signing Gosder Cherilus. However, this line poses more questions than assurance at the moment.

Linebacker Akeem Ayers will supplement whatever pass rush there is up front. He's the star of a group rounded out by Colin McCarthy and Zach Brown.

Jason McCourty is a quality young cornerback who is ably supported by Alterraun Verner. Expect third-round pick Blidi Wreh-Wilson to be the nickel corner. He's got the physical attributes to play in the slot.

Former Raven Bernard Pollard will dole out punishment at strong safety, with Michael Griffin acting as the ball hawk behind him.

Jake Locker needs to reward the Titans' faith in him this season. He's got good targets on the outside in Kenny Britt, Kendall Wright and Justin Hunter.

Tight end Delanie Walker will also be a useful outlet. Yet, his true value might be blocking for the running game. That's good news for Chris Johnson. The graceful, dynamic runner has everything he needs in front of him to get back to his best.

That includes an offensive line reinforced by two powerful new guards. Andy Levitre arrived in free agency, and Chance Warmack was Tennessee's first draft pick.

Both are dominant blocking for the run. Michael Roos is a standout left tackle, while David Stewart is developing well on the right. Fernando Velasco will continue at center.

4. AFC South: Jacksonville Jaguars

The Jacksonville Jaguars have taken some positive first steps toward rebounding from 2012's 2-14 finish. Three members of this year's draft class should make the starting lineup.

Defense

The pieces for new head coach Gus Bradley's hybrid defensive fronts are in place. Former Buccanneer Roy Miller will be vital to the run defense at nose tackle.

Ex-Titans starter Sen'Derrick Marks will man the 3-technique position next to Miller. One-time tackle Tyson Alualu has the size to play the 5-technique role.

The crucial position is the Leo hybrid defensive end/linebacker role. Jason Babin should be the front-runner ahead of Jeremy Mincey. Bradley has suggested Babin fits best at Leo, due to his linebacker experience, according to John Oehser of Jaguars.com.

Paul Posluszny and Geno Hayes will work as an inside linebacker tandem while Russell Allen plays on the outside.

1. NFC West: San Francisco 49ers

Last season's runner-up still looks as powerful as any team in the league. Their top draft pick will start, but continuity will be the key elsewhere.

Defense

The defense is still an intimidating group that practically picks itself. However, the 49ers lack of rotation could be blamed for the unit's struggles in last season's playoffs.

Justin Smith and Ray McDonald are the best 3-4 ends in football. Glenn Dorsey will play nose tackle and attack both A-gaps.

The linebackers are arguably the most talented quartet in the league. Aldon Smith is the primary pass-rusher on the edge, while fellow outside 'backer Ahmad Brooks can do it all.

Patrick Willis and NaVorro Bowman are the heart of this exceptional defense in the middle.

Top pick Eric Reid will replace Dashon Goldson at free safety while Donte Whitner will continue at strong. The only big shakeup should come at cornerback.

This author believes Nnamdi Asomugha will make a strong enough impression in camp to start alongside Carlos Rogers. The 49ers were burned by the Falcons and Ravens in the postseason, so a change is needed in the defensive backfield.

Colin Kaepernick enters his first season as the unquestioned starting quarterback. He'll benefit from having Anquan Boldin to throw to.

The other starting receiver will be Michael Crabtree, whom Kaepernick developed a nice rapport with last season. If Mario Manningham makes a quick recovery from a torn ACL, he'll be the third receiver.

Vernon Davis will remain major part of the passing game at tight end. Rookie Vance McDonald will also feature.

Frank Gore will still be the driving force in the running game, with Bruce Miller leading the way as a blocker.

Joe Staley, Anthony Davis, Mike Iupati, Alex Boone and Jonathan Goodwin form one of the most skilled lines in the game.

2. NFC West: Seattle Seahawks

Matthew Emmons-USA TODAY SportsJesse Williams could play early in Pete Carroll's defense.

The best thing the Seattle Seahawks did this offseason was improve their starting options in the pass-rush department. They added a host of fresh talent along their defensive front.

Defense

That new talent begins with the signing of Cliff Avril. He's a good fit for the Leo end in head coach Pete Carroll's blend of 4-3 and 3-4 fronts.

Chris Clemons tore his ACL in the playoffs, and John Boyle of The Herald claims he might not be fit for the start of the new season.

Avril is the best fit on the outside. On the inside, the Seahawks will likely continue with three hulking tackles.

That means Brandon Mebane on the nose and Red Bryant at the 5-technique. Fifth-round pick Jesse Williams will challenge Mebane for playing time, but it's third-rounder Jordan Hill who could start first.

Hill can play the 3-technique role and offer an inside pass rush. The Seahawks linebackers are all punishing hitters. The trio is led by Bobby Wagner, but K.J. Wright is almost as effective. Seattle's ability to create more pressure could improve thanks to a change at linebacker.

Boyle also suggests Bruce Irvin could see time at strong-side linebacker. That would give the Seahawks a good blitzer at the second level.

Towering cornerback tandem Brandon Browner and Richard Sherman will continue to be the scourge of receivers everywhere. Now-seasoned veteran Antoine Winfield brings his bruising brand of coverage to the mix. He's tailor-made for the slot. Just when you thought Seattle's secondary couldn't get any bigger or more ferocious.

3. NFC West: St. Louis Rams

Rich Barnes-USA TODAY SportsTavon Austin will make an immediate difference for the Rams.

The St. Louis Rams didn't waste their two first-round picks. They'll expect both players to significantly upgrade key positions.

Defense

The front four is already in great shape. Ends Chris Long and Robert Quinn are a commanding pass-rush combination. Michael Brockers and Kendall Langford are tough inside.

The linebacking trio will improve with the arrival of Alec Ogletree. He and Jo-Lonn Dunbar will flank James Laurinaitis.

Janoris Jenkins is a threat to snatch any errant pass. He partners with the more aggressive Cortland Finnegan at cornerback. Fifth-rounder Brandon McGee should beat out the troubled Trumaine Johnson for the nickel corner job.

4. NFC West: Arizona Cardinals

Matt Kartozian-USA TODAY SportsGuard Jonathan Cooper can fix a major area of weakness for the Cardinals.

The Arizona Cardinals caused a stir when they drafted Tyrann Mathieu in the third round. However, there's far more to how they've adjusted their lineups under new head coach Bruce Arians.

Defense

The defense will continue to look ostensibly like a 3-4. That means Dan Williams at nose tackle, and Calais Campbell and Darnell Dockett at end.

Daryl Washington will be the main playmaker on the inside. Alongside him, Jasper Brinkley will add more size at linebacker. On the outside, Sam Acho will be charged with providing the bulk of the pass rush. Fortunately, he's perfectly qualified for the task.

Still, it would help if fourth-round pick Alex Okafor can send O'Brien Schofield to the bench and share the load with Acho.

Things will look a lot different at safety for two reasons. First, there will be no Adrian Wilson creeping up from deep to blitz.

Second, Rashad Johnson won't offer the same kind of dynamism. Any dynamism at safety will have to come from Mathieu.

He's got the perfect ball-hawking skills for robber coverage and man-free looks. Freeing Mathieu to make plays will depend on Patrick Peterson and Antoine Cason locking things down on the outside.

Recently acquired Javier Arenas will feature a lot in nickel and multiple-defensive back looks.

Carson Palmer still has the arm strength to flourish in Arians' vertical passing schemes. Palmer will certainly enjoy firing strikes to a trio of receivers as talented as Larry Fitzgerald, Michael Floyd and Andre Roberts.

Rob Housler has to offer more at tight end. Palmer won't be shy about looking his way on underneath routes.

When the ball isn't in the air, former Steeler Rashard Mendenhall will be required to lead a power-based ground game.

He knows Arians' offense well and is certainly capable of pounding out yards between the tackles. He'll start, but rookies Stepfan Taylor and Andre Ellington will offer a serious challenge. Ellington will certainly feature on third downs. He's got the quickness and receiving skills for the job.

Of course, the success of any plans the Cardinals make in their schemes will depend on how well the line holds up. Arians certainly has faith in left tackle Levi Brown, according to ESPN.com.

On the other side, Bobby Massie will have to put the nightmares of his rookie season to the back of his mind. That might take some time.

However, the Cardinals will be better inside. Selecting Jonathan Cooper with their top pick was a superb move.

Cooper was the best guard in this year's draft class. He's mobile enough to pull around the corner to lead on the power plays Arians loves.

Daryn Colledge may stick at the other guard spot, but Cooper's presence will compensate for that. Lyle Sendlein injured his knee and tore his MCL in Week 12 last season.

The Cardinals need their center ready to play to start the new season.

1. AFC West: Denver Broncos

The Denver Broncos made their boldest moves in free agency and their smartest choices in the draft. They look stronger on both sides of the ball than the team that led the way in the AFC for most of 2012.

Defense

The first major change will involve starting 28th overall pick Sylvester Williams at defensive tackle. Denver's defense needs a more disruptive force at the position, and Williams can be that player.

He'll be joined by more natural run-stuffer Terrance Knighton. The Broncos appear significantly stronger at tackle.

Unfortunately the same is not true at defensive end. The team has so far neglected to replace Elvis Dumervil.

That means relying on Robert Ayers and Derek Wolfe to create pressure off the edge. That should mean fifth-round pick Quanterus Smith can become a valued member of the rotation. He has the outside quickness and rush skills Ayers and Wolfe lack. Of course, the Broncos' pass rush stems mostly from outside linebacker Von Miller.

The game's most complete defensive playmaker will continue to terrorize quarterbacks from a variety of alignments. Signing Shaun Phillips was also a great move and he should win a starting job.

Having Phillips line up at outside linebacker might let Miller see more time at defensive end. In the middle, Stewart Bradley will benefit from a return to a 4-3 after struggling in Arizona's 3-4 base.

The Broncos now boast a big, veteran front seven, and that's just what coordinator Jack Del Rio wants.

Experienced players are also found in the secondary. The great Champ Bailey and newly acquired Dominique Rodgers-Cromartie will be the starting corners.

Rahim Moore and Mike Adams complete a group sometimes lacking in speed but never in smarts.

Peyton Manning proved that he still has enough left to dominate the league. Expect Manning to yet again be among the game's most productive passers.

Protecting Manning is a stellar line led by technically sound left tackle Ryan Clady. New right guard Louis Vasquez will make the group even more impressive.

Manning has great options to throw to at tight end in carbon copies Jacob Tamme and Joel Dreessen.

What Manning will love the most, though, is the fact the Broncos captured Tom Brady's favorite wide receiver, Wes Welker. The intelligent slot ace gives Manning a much-needed safety valve in his declining playing years.

Fortunately, Demaryius Thomas and Eric Decker can take care of making the big plays on the outside. Both have speed to go deep and produce big gains after the catch.

Montee Ball was a smart pick in Round 2 and should start at running back. He's a more than capable pass-catcher, which will suit Manning.

However, Ball is also more consistent as an inside runner than Ronnie Hillman and more dynamic than Willis McGahee.

Jacob Hester offers the perfect combination of skills to play fullback in a Manning-led offense.

He directed the system at Notre Dame and will be surrounded by a host of front-seven talent in the pros. That talent includes Melvin Ingram on the outside. He has to become this unit's featured pass-rusher.

At safety, the Chargers are keen on using former cornerback Marcus Gilchrist at one spot, according to UTSanDiego.com. Having Eric Weddle at the other position will help that transition go smoothly.

Former Jaguars starter Derek Cox will replace Antoine Cason at one cornerback spot. Shareece Wright should win the job on the other side, unless fifth-round pick Steve Williams shines in camp.

This position looks more than a little suspect on an otherwise stout defense.

Philip Rivers should finally eradicate his penchant for mishaps under the tutelage of new head coach Mike McCoy. Yet, it won't just be McCoy who makes a difference.

Rivers will be thankful for a completely revamped offensive line. King Dunlap will feature at left tackle, with Rich Ohrnberger at guard.

Chad Rinehart will play at right guard next to first-round choice D.J. Fluker. That's four new faces around center Nick Hardwick.

Antonio Gates will continue to be a prominent part of the pass offense at tight end. John Phillips will see the field only as a blocker.

Malcom Floyd and Danario Alexander are the kind of big-bodied speedsters the Chargers have collected at wide receiver. Third-round pick Keenan Allen also fits that mold and will contribute early and often as a rookie.

Ryan Mathews has to take better care of the ball and avoid injuries. If he does, he's a 1,000-yard running back.

Danny Woodhead is the best third-down option the Chargers have had since Darren Sproles. Le'Ron McClain is a powerful blocker and decent runner at fullback.

The strength of the offense will be determined by how well Matt Flynn performs at quarterback. McKenzie knows Flynn from Green Bay, but he has not exactly surrounded him with stellar weapons.

Denarius Moore has 1,000-yard ability at wide receiver,but frustrates with his inconsistency. Jacoby Ford has speed but is far from a well-rounded route-runner and pass-catcher.

Juron Criner and Rod Streater complete an uninspiring wide receiver rotation. Things are even less certain at tight end.

Late-round rookies Nick Kasa and Mychal Rivera should compete for the job. Kasa is the more natural blocker, but given the paucity of pass-catching talent, Rivera's receiving skills should give him the edge.

What would help Flyyn the most is a full and productive season from Darren McFadden. He will lead the running game but also give some carries to Rashad Jennings.

Stefan Wisniewski and Mike Brisiel are capable interior offensive linemen. However, Brisiel's experience is in zone-blocking, something the Raiders will avoid in 2013.
